1function C = cs_droptol (A, tol) %#ok 2%CS_DROPTOL remove small entries from a sparse matrix. 3% C = cs_droptol(A,tol) removes entries from A of magnitude less than or 4% equal to tol. Same as A = A .* (abs (A) >= tol). 5% 6% Example: 7% Prob = ssget ('HB/arc130') ; A = Prob.A ; 8% cspy (abs (A) >= 1e-10) ; 9% C = cs_droptol (A, 1e-10) ; 10% cspy (C) ; 11% 12% See also: RELOP, ABS 13 14% Copyright 2006-2012, Timothy A.
